Barnstorm was the group created by
Joe Walsh in Colorado after he left the
James Gang. The original members of the group were Walsh (guitars, keyboards),
Joe Vitale (drums, flute, keyboards) and
Kenny Passarelli (bass). Walsh and Vitale had previously played together in an Akron-based band called The Measles before Walsh joined the James Gang. All of the members contributed lead vocals and songs, although Walsh was the principal singer and songwriter. Later, the group added keyboardists Rocke Grace and Tommy Stephenson. Having two keyboardists permitted Barnstorm to play the complex arrangements live that it was creating through multitracking in the studio or through the use of session musicians such as Paul Harris (piano) and
Joe Lala (percussion).
